Caribou Mountain and the National Forest are named after a man known as "Cariboo Jack," who discovered gold in this area in 1870. He was an adventurous man who became a local legend. Today, the guard station on Caribou Mountain is a haven for adventurers who enjoy a variety of recreational activities.
The guard station can be accessed by car during the warmer months, but only snowmobiles or skis can be used in winter. Guests should be prepared to make the 6-mile trek with all the gear and supplies they need to make their stay comfortable.
Guests at Caribou Mountain Guard Station can enjoy hiking, mountain biking, hunting, fishing, snowmobiling and cross-country skiing. Off-road vehicle trails include the Caribou Mountain ATV Trail and the Caribou Mountain Mine Trail. Click here for an Idaho OHV safety message.
The cabin can accommodate a maximum of 15 guests. One sleeping room is available with a total of six single beds. Guests must bring their own bedding and sleeping pads. A propane cook stove, propane lights and space heater are available, in addition to a supply of propane. A dining area includes a table and chairs. Only a few dishes and cups are provided. A vault toilet and picnic table are located outside.
Drinking water is not provided. Guests are required to bring their own water, as well as garbage bags to pack out their trash. Bedding, dish soap, cooking pots, kitchen utensils and emergency items like a first aid kit are not available.
